Mariners to promote top infield prospect

The Mariners will promote top infield prospect Cole Young this weekend, reports Daniel Kramer of MLB.com. He is not yet on the 40-man roster, so the team will need to make a move in that regard. They’ll also need to create active roster space for Young and starting pitcher Bryce Miller, who’ll be reinstated from the 15-day injured list to start tomorrow’s game against the Twins.

A Pittsburgh-area native, Young signed with Seattle out of high school in 2022. He received a $3.3MM bonus as the 21st overall pick. Scouting reports praised a potential plus hit tool and ability to play somewhere up the middle. While Young doesn’t have huge power projection in a 5’11” frame, he was viewed as a very polished player for his age.

That has been borne out in his systematic progression through the minors. He reached base at a .399 clip between two A-ball levels in his first full professional season. Young spent all of last season in Double-A, batting .271/.369/.390 as a 20-year-old in a tough league for hitters. The M’s bumped him to the more favorable Pacific Coast League this season. Young has taken to it well, running a .278/.391/.463 slash with more walks than strikeouts in his first look at Triple-A pitching.

The lefty-hitting Young actually began his Triple-A career mired in a slump. He hit .200 without a home run over 25 games in April. He’s been on an absolute tear since the calendar flipped. Young has raked at a .370/.466/.680 clip over 118 plate appearances in May. He has connected on five home runs, 10 doubles and three triples among a total of 37 hits. He has added another 15 walks while striking out all of eight times.

Young couldn’t have done more this month to force his way to the big leagues. He has divided his time evenly between shortstop and second base this season. Baseball America wrote over the offseason that he’s likely better suited for second base because of average arm strength. That figures to be his long-term home in Seattle. They’re committed to J.P. Crawford at shortstop. The path to playing time at the keystone is much more open. Ryan Bliss will miss most of the season recovering from biceps surgery. Miles Mastrobuoni and Dylan Moore have split the second base work over the past few weeks.

Moore is having a strong year, though his bat has tailed off following a huge April. He’s a right-handed hitter with a long track record of producing against lefty pitching. Moore figures to take some starts at second base against southpaws, but he’s versatile enough that it doesn’t need to be a strict platoon. Moore can spell Leody Taveras in right field or play regularly at third base over rookie Ben Williamson, who is hitting .246/.278/.297 through his first 38 games. Mastrobuoni, acquired in an offseason DFA trade with the Cubs, carries a .221/.306/.284 line through 111 plate appearances. He’ll be bumped to a utility role if not optioned to Triple-A.

Young was a consensus Top 100 prospect over the offseason. He meets the criteria for the Prospect Promotion Incentive. If he plays well enough to finish in the top two in Rookie of the Year balloting, he could earn a full year of service time. A’s shortstop Jacob Wilson seems as if he’ll run away with the award, but the runner-up spot is still there for the taking. That would not earn the Mariners any kind of draft compensation, which only applies if the team carries a top prospect in the big leagues for at least 172 days.

If he doesn’t earn the top-two Rookie of the Year finish, Young will fall short of a full service year and remain under club control for at least six seasons beyond this one. He’d be well-positioned to qualify for early arbitration as a Super Two player during the 2027-28 offseason if he’s in the big leagues for good.
